In my observation, DOZE works for me especially at night. But in daytime where you use the phone all the time you cant feel it.
The System UI Tuner (Excited at first, but eventually I realized that its useless for ME)
Turbo Download (I tried but it didn't work for me, because when you turn on your Data and WIFI, either of the two will work. I expect that both DATA and WIFI will work for faster download )
Improve App Permission (Its a little bit annoying for me)
Force Restart (Useful for me)
